Dan and Jennifer Bauer's '67 Chevy pickup, with its trick four-link front suspension, lockers and 4.56:1 gears, almost made it up "Nasty'' on the White Trail, but didn't quite make the full jump over the 3-foot-high obstacle, landing squarely on the rear driveshaft. Dan made a new shaft back in camp and rejoined the trail ride the next day.
